Objective To investigate the factors influencing the patency rate after PTA for arteriovenous fistula stenosis. Methods A total of 62 patients were selected as study subjects, with examinations conducted at our hospital from January 2023 to December 2024. All patients underwent PTA for arteriovenous fistula stenosis. Based on examination results, they were divided into the unoccurred group (with patent fistula at re-examination) and occurred group (with non-patent fistula at re-examination) to compare factors affecting patency rate. Results The number of hypertensive patients in the non-stenosis group was significantly higher than in the stenosis group, indicating a certain association between hypertension history and post-PTA patency rate (P<0.05). Hyperparathyroidism increased the risk of postoperative restenosis (P<0.05). Inflammatory response was a factor influencing postoperative patency rate (P<0.05). Blood glucose levels affected postoperative patency rate (P<0.05). Patients with better nutritional status had a lower risk of postoperative restenosis (P<0.05). Total cholesterol influenced postoperative restenosis (P<0.05). Dyslipidemia may be associated with postoperative restenosis (P<0.05). Conclusion This study identified six factors affecting post-PTA patency rate for arteriovenous fistula stenosis: hypertension, parathyroid hormone, inflammatory response, blood glucose, albumin, and triglycerides. These factors require focused control to facilitate subsequent recovery.
